Berit. known that I, JOHN J. TATUM, `a

citizen of the United States, residing atV Baltimore, State` of Maryland, haveV in- Vented certainv new and vuseful Improvements in Stake-I-Iolders rfor Flat-Cars, of .which the following is a specification.

Inpractice, it has been found that with stake holders of the type now commonly employed, the stakes work loose and sometimes entirely out of the stake holder under the Vibrations of the'cars. This is particularly likely to occur When temporary rsta-kes are driven into the pockets to support lumber and like materials that are being loadecl upon the cars because these temporary stakesl are-more or less roughly fashioned, do not fit the stake holders accurately and inmany-.instances do not project into the stake holders to the full depth of the latter.

It is a matter of the highestimportance to provide stake holders that will with certainty hold the stake against. accidental dis- -lodgment therefrom because it has sometimes happenedl that stakes have become dislodged from cars-loaded with lumber and v'pieces ofthe lumber-have, under Vthe on anothertracka'nd serious wrecks have resulted therefrom. f v

It is, therefore, the-primaryjobjectV of the present invention to provide a stake holder-.fV

which will efectually hold a stake securely therein no matter how roughly the latter may be fashioned.

A further object of the invention is to provide a stake holder which will effectually serve the foregoing purpose but which will be of simple construction and economical to manufacture.

Further objects andadvantages of the inscription which now follows:

In'V the form, of. ltheiinvention illustratedl in Figs. 1 and 2, the stake :holder is embodied in an'integral structure .comprising securing, flanges 10 and the central off-set body por-U tion 11, the sidewalls 12 of thelatter being continued. below the front wall lfthereof. The inner faces of thesideywalls 12. and the inner faces of the front wall 13 are'provided with horizontal under-cutvrib's 14.,

It is'not essential that'the front walllr befterminated short? of thefbttom' of. the i the holder, thefact that the stake Vprojects somewhat belowrthe1front1wall-13 renders itfflpos'sible to drive upwardly upon the lower end of the stake. However, it is to be understood that the invention contemplates making the front wall 13 as deep as the side walls 12. i 'p In the form of the invention illustrated in Figs. 3 and 4, the stake holder embodies securing flanges 20 and a central U-shaped body portion 21 constituting af receiving .of the body portion and the side walls-23 1 thereof are studded with barb like projec- 'tions disposed in staggered vrelation andr comprising the curved and inclined faces 24 and flat, horizontal, under faces 25. These barb dlike projections may be formed by striking them from the material of the front and side walls as vclearly illustrated in Fig. 4. It is apparent that the Shape of the barb like projections illustrated in Figs. 3 and 4 is such as to permit downward movement of the stake holder but to resist upward move- VSide walls 12 but I.,.findsnch an arrange-p.: i mentlofpartsof.advantage'sincej if it-be-f.. 1 comes necessary to removefrthegstakefrom pocket for the stake.

In the form of the invention illustrated in Fig. 5, the stake holder comprises the securing flanges 30 and the ofi'lsethody 31 'eorresponding in a general Way to thestructure` illustrated inFigs. l and 3. In this mod1- W fied iform .of the inventon, however,'sen 1i-r spherical bosses 32 are struck, or otherwise formed upon, the front and side walls-33 and i 34, respectively of the body portion. p These bosses serve/to bite into'V a stake and ito aid in preventing the dislodgmentoffthe stake from the stakeholder.V

Inx the modified form of'r the invention--` illustrated in Figa', the stake holderi` is, in

its general form,- substanti-ally like the. stake; holder shown in Figs. 1 and '2, except tha-tJ tions ofthe invention, theseveral types ofholding devlces employed are. disposed1 inV such manneri that=they willEieng-age a lstake| even though the latter be so roughly' fashioned that it Vwill project alflthezway throughthe body portion: of: .the stake holder.
